We investigate the spatially optical solitons shedding from Airy beams and anomalous interactions of Airy beams in nonlocal nonlinear media by means of direct numerical simulations. Numerical results show that nonlocality has profound effects on the propagation dynamics of the solitons shedding from the Airy beam. It is also shown that the strong nonlocality can support periodic intensity distribution of Airy beams with opposite bending directions. Nonlocality also provides a long-range attractive force between Airy beams, leading to the formation of stable bound states of both in-phase and out-of-phase breathing Airy solitons which always repel in local media.
我们通过直接数值模拟研究了非局域非线性介质中艾里光束产生的空间光学孤子以及艾里光束的异常相互作用。数值结果表明,非局域性对艾里光束产生的孤子的传播动力学有深远影响。研究还表明,强非局域性能够支持具有相反弯曲方向的艾里光束的周期性强度分布。非局域性还在艾里光束之间提供了一种长程吸引力,导致形成同相和异相呼吸艾里孤子的稳定束缚态,而在局域介质中它们总是相互排斥的。
